Can you harden polymer clay with a hair dryer?

Polymer clay is a popular medium for artists and crafters due to its versatility and ability to create intricate and detailed artworks. When working with polymer clay, one may wonder if alternative methods, such as using a hair dryer, can be used to harden or cure the clay. In this article, we’ll explore whether using a hair dryer is an effective way to harden polymer clay and discuss the potential advantages and drawbacks of this approach.

The Curing Process of Polymer Clay

Polymer clay undergoes a curing process that involves a chemical reaction triggered by heat. The heat causes the plastic particles in the clay to fuse together, transforming the soft and pliable material into a durable and solid state. This curing process is typically achieved through baking the polymer clay at specific temperatures and durations.

Using a Hair Dryer for Curing

While a hair dryer can generate heat, it is generally not recommended as a primary method for curing polymer clay. There are several reasons for this:

  • Inconsistent Heat: Hair dryers blow warm air, but the heat distribution may not be consistent or evenly distributed. This can lead to uneven curing and potential areas of the clay remaining undercured.
  • Temperature Control: Hair dryers do not provide precise temperature control, which is crucial for proper curing. Polymer clay requires specific temperatures to achieve a durable and long-lasting finish.
  • Extended Curing Time: Using a hair dryer for curing polymer clay may require significantly longer exposure times compared to baking in an oven. Prolonged exposure to heat can lead to other issues, such as scorching or burning.
  • Unpredictable Results: Relying solely on a hair dryer may yield unpredictable results and may not produce the desired level of hardness and durability in the clay.

The recommended and most reliable method for curing polymer clay is to use a conventional oven or a dedicated polymer clay toaster oven. Follow these steps for successful curing:

  1. Preheat the oven to the temperature recommended by the manufacturer of the polymer clay.
  2. Place your polymer clay creations on a baking surface, such as a ceramic tile or a baking sheet lined with parchment paper.
  3. Bake the clay for the duration specified by the manufacturer, usually around 15-45 minutes, depending on the thickness of the clay and the brand.
  4. Allow the clay to cool completely before handling or finishing your project.


In conclusion, while a hair dryer generates heat, it is not a recommended or reliable method for curing polymer clay. Proper curing requires consistent temperatures, precise control, and specific durations to achieve the desired hardness and durability. Using a conventional oven or a dedicated polymer clay toaster oven is the best approach for achieving optimal results when curing polymer clay. By following proper curing techniques, you can ensure that your polymer clay creations are fully cured and able to withstand the test of time.
